Cussler began writing novels in 1965 and published his first work featuring his continuous series hero, Dirk Pitt, in 1973. His first non-fiction, The Sea Hunters, was released in 1996. The Board of Governors of the Maritime College, State University of New York, considered The Sea Hunters in lieu of a Ph.D. thesis and awarded Cussler a Doctor of Letters degree in May, 1997. It was the first time since the College was founded in 1874 that such a degree was bestowed.

Cussler was an internationally recognized authority on shipwrecks and the founder of the National Underwater and Marine Agency, (NUMA) a 501C3 non-profit organization (named after the fictional Federal agency in his novels) that dedicates itself to preserving American maritime and naval history. He and his crew of marine experts and NUMA volunteers discovered more than 60 historically significant underwater wreck sites including the first submarine to sink a ship in battle, the Confederacy's Hunley, and its victim, the Union's Housatonic; the U-20, the U-boat that sank the Lusitania; the Cumberland, which was sunk by the famous ironclad, Merrimack; the renowned Confederate raider Florida; the Navy airship, Akron, the Republic of Texas Navy warship, Zavala, found under a parking lot in Galveston, and the Carpathia, which sank almost six years to-the-day after plucking Titanic's survivors from the sea.

In addition to being the Chairman of NUMA, Cussler was also a fellow in both the Explorers Club of New York and the Royal Geographic Society in London. He was honored with the Lowell Thomas Award for outstanding underwater exploration.

Cussler's books have been published in more than 40 languages in more than 100 countries. His past international bestsellers include Pacific Vortex, Mediterranean Caper, Iceberg, Raise the Titanic, Vixen 03, Night Probe, Deep Six, Cyclops, Treasure, Dragon, Sahara, Inca Gold, Shock Wave, Flood Tide, Atlantis Found, Valhalla Rising, Trojan Odyssey and Black Wind (this last with his son, Dirk Cussler); the nonfiction books The Sea Hunters, The Sea Hunters II and Clive Cussler and Dirk Pitt Revealed; the NUMA® Files novels Serpent, Blue Gold, Fire Ice, White Death and Lost City (written with Paul Kemprecos); and the Oregon Files novels Sacred Stone and Golden Buddha (written with Craig Dirgo) and Dark Watch (written with Jack Du Brul).

Clive Cussler died at his home in Scottsdale, Arizona on February 24, 2020.

Like every Clive Cussler (R.I.P.) novel in general and NUMA Files novel in particular I've read, fun and entertaining. However, some glaring flaws too:
(1) The ending seems rushed and feels a tad incomplete, especially regarding the ultimate fates of the key villains.
(2() It seems a tad hard to believe that the Asian characters--Chinese and Japanese alike--use the English measurement system instead of the metric system, and that every single one of then speaks absolutely perfect English--SAT words and slang phrases alike--with not only the Western characters but even amongst each other.

That said, Akiko is a very likeable supporting character; she reminds me a bit of the Aki character (portrayed by Akiko Watanabe) in my favourite 007 film "You Only Live Twice."

I could totally picture either Steven Bauer or Dave Batista playing Joe Zavala in a filmic adaptation.

After reading umpteen Clive Cussler novels, I've run out of laudatory resources to describe them. Suffice it to say: His works are definitely worth checking out, unless you're not a fan of action stories.

The sea levels are rising, and nobody knows why. The usual bureaucrats are bungling. Kurt Austin and Co. start investigating, only to come up against a legendary yakuza assassin, and the Chi-coms.

Lots of globe trotting and action. The Numa Files isn't my favorite Clive Cussler series, but this book is one of the better ones, I think.

Clive Cussler and his writing team have found the perfect recipe for a successful book. Take a world wide disaster of some sort...add an evil villain who is generally richer than God and looking for something or someone to dominate...sweeten with a beautiful woman to help along the way...and stir in a generous helping of heroes and you have all the ingredients to save the world. [The Rising Sea] is no exception. It is believable and has the usual bits of history and current day events blended to produce another great read.

This was a fun book to read; I enjoyed it quite a bit. It was (clearly) a fast read for me; it held my interest and had decent character development of the extended cast of characters. It also has plenty of humor and banter between the characters (I think I love the banter between Gamay and Paul Trout the most, I think, although Kurt's and Joe's back-and-forth's can also be fun). Akiko was a great "supporting character" and I enjoyed her development fully over the course of the story.













I enjoyed this book. It was a lot of fun to read, and it was truly a fast read. I had a hard time putting it down, and I am glad I took a chance to continue reading books from this alternate series that Clive started to tell stories about other NUMA adventures because Dirk and Al were probably too old or somewhere else in the world for when these adventures would have been taking place.

Interesting read, but all his books are interesting. It makes me think, could this truly happen, and the answer is a resounding YES!

Given the right circumstances any thing is possible, right??

I liked the history lesson on the samurai swords & the legend behind the men who made them.

The AI that the Japanese designed, reminded me of " I, Robot ", which makes me wonder is this the way technology is heading. Robots that look & act human.

Wow, this just blows my mind, but I can see it happening.

Another thing, is our ocean sea levels rising, and if so what is being done to stop it, & is it humans that's doing the manipulating.

So much to think about, which is why I love me some Clive Cussler. He makes you go, hmmmmmm!

Anyway, these are my thoughts on his latest novel, The Rising Sea.

Reading is my life, so I'm off to another adventure & as always.

You already know, Happy Reading!!!!

I really enjoy Clive Cussler's format. Historical intro then moves to present day and great adventure along the way. But in the last three books I've read (one was Oregon Files series) are all situated in this same region; the Pacific area. Can we move the story to somewhere else please.

Fifteenth in the NUMA Files action thriller series and revolving around Kurt Austin and Joe Zavala, a pair of troubleshooting good guys.

My Take
It’s a political greed to be top dog that threatens the world with a futuristic technology. On the flip side, there’s a fascinating reveal on a small group who are anti-e-tech, which comes at an interesting point in our own time, what with identities being stolen from Facebook and others. Then I took a leaf from Kurt’s observations…and yeah, I do carry quite a bit of “junk”. Hmmm

I certainly felt a shiver rush over me when I read of the electronic shutdown in Shanghai! Eek. And, lol, there’s plenty of James Bond-type moments, such as Paul and Gamay’s efforts to get the data out to America! Whew. Got to thinking Mission Impossible as well with Kurt, Joe, and Nagano's flight off the island. Oy...these boys know how to live it "up", lol.

On the technical side, The Rising Seas uses a multiple third person point-of-view, as Cussler/Graham are providing perspectives from a range of characters on both sides of the conflict.

A metaphor at the start compares America with the game of Go, as an interesting lesson for Han. That's followed up with the twist at the end that raises up shades of a Terminator-style world! Sure hope they cut those batteries!

As usual, Cussler/Brown combine plenty of action with several storylines, all of which blend together along the way with an enemy who attempts to use Kurt and Joe as their very own red herrings. You’ll definitely want to be flippin’ them pages!

The Story
A battle between politicians and scientists is cut short with Kurt Austin’s dramatic entrance. With more stunned silence when Austin proclaims the truth of the global melting, the waters rising, the flooding threatening the coastline.

It’s a truth that sends Kurt Austin, Joe Zavala, and the rest of the NUMA scientific team rocketing around the globe in search of answers. What they find at the bottom of the East China Sea, however, is even worse than they imagined — and part of a diabolical plan to upset the Pacific balance of power — and unexpectedly displace as many as a billion people.

A rare alloy, a pair of five-hundred-year-old Japanese national treasures, an assassin so violent even the Yakuza has disowned him, an audacious technological breakthrough that will become a very personal nightmare for Kurt Austin — action that ranges from the shark-filled waters of Asia to the high-tech streets of Tokyo to a forbidden secret island — the NUMA team must risk everything to head off the coming catastrophe.

The Characters
Today
Kurt Austin, Head of Special Projects, and Joe Zavala, an engineering genius, are partners who work for NUMA.

NUMA is…
…short for the National Underwater and Marine Agency, whom many on Capitol Hill consider a cowboy organization. NUMA monitors the world’s oceans and America’s lakes, rivers, and waterways as well as historical work. Paul Trout is a geologist specializing in deep-sea studies and married to Gamay Trout who is a marine biologist. Rudi Gunn is the assistant director; Dirk Pitt is the director. Hiram Yaeger is the resident computer genius who designed Max, a unique computer with a sense of humor. Robert Henley is a marine geologist under Paul. The brilliant Priya Kashmir is restricted to a wheelchair, but that is her only restriction.

Vice-President Sandecker used to be director of NUMA.

Greenland is…
…but one frigid land that Kurt visits. Vala is a Norwegian geologist who helps out on the Navik Ice Sheet.

China

The Serpent’s Jaw is…
…a canyon in the East China Sea off Shanghai where an underwater mining operation is located. Dr. Chen and Commander Hon Yi of the People’s Liberation Navy are the only human operators. Golden Adamant (GA) is a new, very rare alloy. Wen Li is small and very old, but only physically. Politically, he’s Lao-shi, an old person of high skills, a major powerhouse in China.

Walter Han is über wealthy and a powerful man in China and Japan. Industrial Technology, Inc. (ITI) is the business his father built. Gao-zhin is their best engineer and slides into Han’s new company, China-Nippon Robotics. Ny-Nex is a female automaton you’d never know was a robot.

Shanghai
Melanie Anderson is the reporter for INN, Indie Network News, that thrives on conspiracy theories. Charley is her cameraman. General Zhang ( Nighthawk , 14) is based at the Ministry for State Security.

Japan is…
…a target, a US ally. Superintendent Nagano is in charge of the Yamana Police Station. Honshu is an island abandoned some years ago.

Kenzo Fujihara is a Japanese geologist who eschews electronic technology. Akiko is one of Master Kenzo’s students and considers herself his bodyguard. And does she ever have the fascinating past! Ogata is on another station. Ichiro is one of Kenzo’s earliest followers.

Ushi-Oni, a.k.a., Oni, loves to kill and defected from the Yakuza, a ronin, and a cousin twice-removed from Walter Han. Hidekai Kashimora is a Yakuza underboss who runs Sento, a gaming, drug, and prostitution establishment that includes a combat arena.

1945, Japan
Sergeant Coldy Bimore received a precious shipment. Iemasa Tokagawa was the latest in his family to protect priceless katanas, including the Honjo Masamune.

Winter 1573, Central Japan
Yoshiro Shimezu is a samurai angry with his overlord. He wields the katana Honjo Masamune. Kasimoto is the brutally tyrannical Shogun who wields the katana Crimson Blade.

Masamune was Japan’s greatest swordsmith and he created the Honjo Masamune. Muramasa was Masume's envious protégé who created the bloodthirsty Crimson Blade. Both blades became national treasures, and then they disappeared.

Ringwoodite is a stone that traps water.

The Cover and Title
The cover is a complement of dark blues versus an orangey yellow in a dark roiling sea with its waves rolling up on the golden beach, a leather-wrapped katana sunk into the sand. The primary author’s name is at the top in an embossed white outlined in a metallic light blue — the title is in the reverse colors, embossed, and at the bottom of the cover. The secondary author’s name is very small in a gray to the bottom right of Cussler’s name. There’s more gray in both bits of series information while the info blurb is at the top in white.

The title is the fear, a future of The Rising Seas drowning the world.

Typical Cussler adventure yarn that takes you to foreign countries and an undersea venue. A quick beach read with, alas, a very unsatisfactory ending.

Clive Cussler was an amazing author who infused his love of the ocean, fast-paced action, and masterful storytelling to create some of my favorite work of fiction. I with fondness can still recall the plot, action, scenes, and witty lines of Dirk and Al in their adventures even 20 years after reading one of their stories...

Graham Brown is no Clive Cussler.

This story fell flat and continues to reinforce my belief that Clive Cussler was not reviewing much if any of these before printing. Having lived in Japan (Shizuoka Prefecture) for 3 years, much of the story's stage created a sense of cringe and nausea. Nothing felt genuine, believable, or even practical with respect to many of the Japanese characters or the nation.

The plot itself felt disconnected from anything traditionally bound by NUMA, with it's eventual resolution too simple and casually commented on at the end to drive any sense of thought or learning. That these are NUMA agents may be the most unbelievable plot point...

I often wondered if Mr. Brown understood who the main character is in the story. Like with Dirk/Al, Kurt is the main character and Joe his faithful sidekick - yet at points I felt that this was confused or convoluted. I genuinely enjoy the Al focused chapters in CCs books, and am curious to see more the sidekick's view...but it should never eclipse our main hero.

*Spoilers below*
Every scene in Japan felt as though it was intended to be written for an American or Euorpean setting. The casual use of English between side characters who had no reason to know let alone use English, Americanesque responses to questions or actions, even how the Author had Akiko flirt in the club. In fact, the character of Akiko may have been one of the most egregious failures of this author with respect to all things Japan - her character alone almost had me stop reading, such drivel and not realistic to Japanese cultural norms.

As far as language examples, when we are on Hashima Island, the patrolling soldiers were speaking English to one another...why? Oh, so that Kurt or Joe's witty "boss wants you here" line can be used and the plot could continue... bleh. The author himself seemed to realize (or an Editor tried to correct) some of this, when in the final pages of the book characters began to miraculously leverage their native languages of Mandarin/Japanese in speaking and reading again.

One aspect that should have bothered others throughout the story was the lack of any connection the Sea. With an organizational name like NUMA, and the history of both Kurt/Joe and their greater predecessors Dirk/Al, why did it take until the final chapters (93% into the book) before our main characters even ended up in the water? Even then, it's only to swim from a boat to the shore so that the story can continue.

The plot driver (massive oceans under the curst) is something I actually had heard of prior to reading this, and so immediately thought that the likely culprit of the rising oceans when tied together to a mining expedition that didn't shut down... so there wasn't a great deal of suspense for me in the reveal.

I rather expected that the Golden Adamant found extracted be used to seal the damage done by the Chinese off-shore mining, a fitting symbolism of a metal being extracted for the purposes of war to be used to save the world/environment. Instead, we are treated to a throwaway sentence at the conclusion of the book about "western nations gaining the alloy in a dormant volcanic region of Japan."

There was one interesting plot point that should have been used as a flashback - it could have been an incredible driver of the story. In the first 1/3 of the book there is a scene where Walter Han and Oni are discussing the backstory of Japanese swords at the end of WW II, and the American sergeant who may have absconded with the sword. I actually thought this would have been a great chapter 2 flashback, something that could have connected to Kurt's efforts and maybe led to his discovering the Sgt was real and had hidden with the sword in one of Mt Fuji's 5 lakes to protect it for the Japanese people. Kurt could have dived the lake, found the soldiers grim skeleton clutching the sword, an American protecting this Japanese historic relic for future generations and a showcase of the respect an average American had for Japan even right after the war. Great potential in that story, and something that could have really driven the plot, action, and created a sense of pay off at the end.

But we had Graham Brown as the author...

This book kept me somewhat intrigued to find out exactly what was causing the "Rising Sea," but other than that, the book was flat. The characters were difficult to distinguish from one another. The women were vapid, and all of the male characters loved beautiful women and cars. No one was interesting. That being said, this is a fast-paced thriller, so the plot is itself the main character.
I gained more respect for this novel when I learned that the author himself lived a life not unlike the characters in the book, which is very cool. And the author is primarily a scientist/adventurer, and secondarily an author, which makes me forgive him for the literary pitfalls.

Not a good mystery, not a good historical novel, but an excellent adventure story.. if you like people that get themselves into impossible situations and are able to get out of them by impossible means, these books are meant for you. These are just excellent reads that take no thought process and little, if any, scrutiny. The Kurt Austin series is propelled by NUMA ( National Underwater Marine Agency). This is a non-political agency that has strong ties to the U.S. Government. In this case they are called upon to find out why the Oceans are rising at an alarming rate. This takes them on a journey to Japan and China. Again, this an adventure novel that is fun to read but with little substance.

The Cussler formula of NUMA confronting and ending a megalomaniac villain’s plans while uncovering some secret, relic or mystery continues here…A Chinese leader and Chinese Billionaire’s plan for Chinese technological domination threatens the World through rising seas and the unearthing of a priceless Samurai sword are the key elements here for NUMA to confront…Good stuff!

An adventure story that covers Japan and Shanghai. What does rising sea levels and an ancient sword have to do with this story? A corrupt government and former Yakuza hitmen as well. This is a very solid story of how NUMA forces from Washington DC tackle this adventure.

Sitting somewhere between "Sahara" and "Blue gold" in terms of nautical armageddon and heavily modeled on "Dragon" with its Sino-Japanese setting.

The nautical armageddon stays too far in the background and the setting lacks cultural flavour, so both sit uneasily on top of.. Not enough Akiko!

As usual with Clive Cussler, this is a fast paced, rollicking novel of derring-do. This time with evil Japanese yakuza and greedy Chinese officials on one side and goody-two-shoes shogun/samurai monks and priests on the other! Not to mention the dodgy submarine oceanographic geomorphology that spins the whole story.
